FlowZone Shower 4-Gallon Lithium-Ion Battery Powered Roller/Backpack Sprayer (3.6V/2.6A Spray Gun)

This works great. My husband uses it to put solution on our sidewalks to help get rid of mold. Makes the job easier

When this works, it works well. Unfortunately, over a period of nearly a year, I had three things go wrong: first, the long wand, supposedly made of stainless steel, developed pinhole leaks. I was using a vinegar/salt weedkiller, but it shouldn't have affected the stainless steel. They sent a new wand, and I started rinsing it and the gun out with water after each use. Then the gun died--I charged it after using it, and the next time I went to use it, it was dead. They sent another one. Then I went out to use it one day and it wouldn't pull liquid up through the hose and out the gun. No leaks or clogs, so I suspect the gun wasn't pulling enough of a vacuum. At that point, after 11 months, I felt I couldn't rely on it, so I sent it back and received a refund.They only have one customer service guy, Connor, and while he's pleasant enough to talk to, he often doesn't return voicemails or emails (or maybe he was just getting as tired of hearing from me as I was of contacting him). If I were going to buy a FlowZone sprayer, I'd get the more expensive model with the 5-star reviews. However, most of the battery-powered ones have various complaints. I'm going to try the Tomahawk Power gas-powered model.

I own a back pack sprayer and after 4 fill ups I certainly feel the struggle.Purchased this to lighten the load on spray days.Pros:It does have a decent spray rate and I can quickly cover areas.The nozzle on the long wand has an adjustable spray from misting to stream. Because of the velocity and twisting the nozzle a little past mist I have confidently sprayed very close to plants without over spray. Certainly closer than I would with the pack back.The quick connect system allows you to position swivel the direction the wand end points. Setting the nozzle outwards means I can walk a bush line without twisting my hand to get the spray underneath.So far I have been able to get 2 full fills a couple of times with enough battery juice to run water through on the clean up.The tank does not pressurize so the fill up cap is easy to take off on next refill.Clean up is easy as almost every piece comes apart and you can stream a hose though everything. Cleaning the handle does require the battery (pull trigger while holding hose at the base connection) which could be an issue if the battery ran out. Probably have to make a conscience reminder to charge then clean otherwise.The onboard tool holder is great. It will accommodate both the wand and the short nozzle and the handle holder keeps the handle tight during transport.Cons:I have had some issues with leaking from the 'air vent' (small valve on the hose side). When full it does splash and dribble out (pictured). I pulled the unit over accidentally and the fluid jetted out of that same vent. It will also splash on the back of your leg if the ground is bumpy enough until the fluid level drops. I have never filled past the 4g line.You have to be aware that releasing the trigger that sometimes it continues spraying. It only lasts a second but it could be enough to get it somewhere you didn't want.The wheels certainly could have been either bigger or pneumatic. I have a farm so the terrain is not pristine and hitting lumps and bumps causes stability issues.Has some issues with the wand dripping when parked (pictured). It isn't a constant flow but will drip. I am not using it on a manicured lawn so the odd splash or drip isn't a huge thing for me.The hose that attaches to the handle will pull off the barbed connector if strained (pictured). I will probably attach a clip over the connector. That has resulted in fluid leaking whatever was sucked into the hose on the grass.This also means for me it will not work for spraying trees but works fine for ground spraying.I am no longer lugging a backpack around but I do get elbow fatigue with pulling the cart around. More so when the ground is bumpy. Each bump tugs on the arm.Getting only 2 fill ups per charge would probably work for most homeowners and it does go fast which is nice. I am guessing it has cut my time in half.I would recommend this with the warning of the splashing leak. Obviously more of an issue if you have a meticulous lawn.I will update if anything changes.

First impression was that it was rather cheaply made, but I decided to give it a try and liked the performance. The spray was strong enough reach a decent area of the deck, the charge lasted for a long time and it was easy to roll around. It can wander like a puppy and tips over easily, but that wasn't a deal breaker for me. Then the wand broke off while attached to the power head making the sprayer unusable in the middle of a big project. I contacted customer service, they were nice and agreed to replace the part. It took a long time to get the package, only to find out that they sent the wrong part. Another few emails and another part was on it's way. This time they sent a package that should have gone to someone else. We shipped back the wrong package and waited again for the part. After many weeks, we ultimately received the right part and finished the project. I rinsed the sprayer, dried it and put it away for the winter in a weatherproofed pool shed/sauna where we store mechanical things for the winter. This spring I discovered that the metal on the sprayer had rusted - although nothing else in the shed had any signs of rust. I've contacted customer service and sent pictures - asking for replacement parts, but radio silence. Bottom line - buy something else.

I just completed spraying Spinoza dissolved in water on all citrus trees and garden vegetables. I used only two gallons and took about 15 minutes.I sprayed several citrus trees, mature tomato plants and an assortment of other vegetables. This battery powered sprayer performed beyond expectations. Using the roller wheels far better than shoulder mount but the option is there.Some of the best performance is:1. Battery operated/battery life.2. Steady consistent spray pattern.3. easy to maneuver in garden area.4. Extended spray want easier to spray underside of leaves.5. Adjustable spray patterns for different applications.6. The pigtail hose from the tank to the sprayer has sections of coiled wire inside to prevent kinking at the connections.Best of all NO MORE HAND PUMPING.

Not the best product.It would be good for people that need very low pressure (my $10 pump spray give me more pressure)...the 4 gallon container with the carrying handle is great but the electric spray head is crap, it gives very low pressure and if you stop spraying it wouldn’t spray again unless you play with it for few minutes
